I used to read on my Palm Zire 72... and I still have the books there... Now I just want them on my Ipod in the same format.

You mentioned eReader format. The copy protection (DRM) system in the eReader format works by requiring you to enter the name and CC Number used to encrypt the file, usually the one used to pay for it, but in any case, the one entered into fictionwise's system when the file was downloaded.

If you have the book(s) that you want to read on your PC, then you can upload them to your Personal Bookshelf at Fictionwise and download them from there to the iPod Touch. Somewhat back to front, but it does work (gets tedious mighty quick). There are other ways but none of them terribly straightforward because a simple web server doesn't work as eReader requires a ereader:// formatted link (don't ask).
